CENTRIFUGAL ORE-SE'PARATOR.

SPECIFICATION forming part of Letters Patent No. 489,200, dated January 3, 1893 Application tiled April 24, 1891.

To all whom it may concern.-

Be it known that I, ORRIN B. PEoK, a citi'- zen of the United States, residing at Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Centrifugal Ore-separators, of which the following is a specification.

The object of my improvement is to provide means for more thoroughly and effectually Io separating the particles of the material being treated, and this I accomplish by constructing a machine which combines the qualities of the various belt separating machines and the centrifugal separating machines; and my invention consists in the features and details of construction hereinafter described and claimed.

In the drawings, Figure 1 is a vertical central section of a machine embodying my imzo provements; Fig. 2 a cross section in an enlarged scale on line i. 2 of Fig. 1, looking in the direction of the arrows; Fig. 3 a section on line 3 of Fig. l, looking in the direction of the arrow; and Fig. 4: a section on line 4 of z5 Fig. 3, looking in the direction of the arrow.

In constructing my improved machine, I provide a vessel A, of suitable form and di xnensions to receive the parts to be contained l therein, as hereinafter described.l I mount 3o this vessel upon a shaft B, by means whereof it is supported and revolved, and I preferably inclose it by a curb C', or other suitable device.

Within the vessel I place one or more belts D, supported upon traveling rollers E, preferablylsupported in journals 1', secured to the vessel. One of these rollers is preferably made movable for the purpose of adjusting the tension of the belt, as shown in the drawings, more particularly in Figs. 1, 3 and 4.

For the purpose of driving the rollers to cause the belt D, to travel, I provide a properly fjournaled shaft F, carrying a suitable belt pulleyf, and upon this shaft I mount a beveled gear G. 'lhis beveled gear meshes, as shown, with beveled `gears G', mounted upon suitably journaled shafts g'. On these shafts I mount sprocket wheels 1l, over which pass sprocket chains Il', which also travel 5o over sprocket wheels Limountcd upon the rollers over which the belt travels.

By this means, as the shaft F, is revolved'by any suitable power, the rollers will be driven and the belts caused to travel over them. I preferably secure to the shaft a suitable receptacle J, into which the water and material to be treat-ed are introduced by means of a pipe, as J In operating the machine, I revolve the vessel A, together with the parts contained there- 6o in, and at the same time impart a revolution -to the shaft F, in the same direction with the vessel, but at a rate of speed varying slightly from that of the vessel, in order to secure a slow travel of the belts D. The belts travel .in the direction indicated by the arrows, and as the water and material are received into the receptacle J, they are discharged upward and outward therefrom -by centrifugal force and deposited upon the surface of the belts, 7o over which they pass. As the water and materials pass over the surface of the belts, the heavier particles are caused, by the action of centrifugal force, to adhere to such surfaces,

and are carried down and around by the travel of the belts, until they reach a point where the action of the centrifugal force upon the particles tends to remove them from the surface of the belts. It will thus be seen that the rotatable vessel A serves mainly asa frame 8o work, to contain and support the Separating belts and as a means of carrying them around the axis of rot-ation. I desire to be understood, therefore, that in speaking in the specification and claims of a revoluble vessel I85 mean something, capable of receiving and supporting the separating belts andcarrying them around a common center of rotation.`

s As above described and as shown in the drawings, the belts D in the vessel A travel 9o around their rollers, while they are at the same time carried around by the rotation of the vessel in which their rollers are arranged. I consider that" the employment of belts which travel while being rotated or carried around in a circle as the gist of my invention, and I do not desire therefore to limit myself to specific forms of construction, so longas this idea is employed.

I claim:

IOO

1. In centrifugal ore-separators, the combination of a revoluble vessel=- and one or more traveling belts inside the vesselv and revolving therewith, substantially as described.

2. In centrifugal ore-separators, the combination of a revoluble vessel, one or more belts insie the vessel simultaneously traveling in one plane and revolving in another, and means for imparting said motions to the vessel and belts, substantially as described. Y ORRIN B. PECK.
